Application filed June 5, 1899. Serial No. 719,468. (No model.)

To all whom Vt may conce-rn.-

Beit known that I, DENroN SIMrsoN, aA citizen of the United States, residingat Centre, iu the county of Howard and State of Indiana, have invented, anew and useful Corn` Planter, of whichthe following is a specilisists in the novel construction, combination,

and arrangementof parts Ahereinafter more fully described, illustrated, and claimed. A.Vihile the essential features or" the inven-A tion are necessarily susceptible to modicationswithout departing ffrom the spirit or scope thereof," still the preferred embodiment of the same'isishown inthe accompanying drawings, in which- Figure 1 is a front elevation of a portion of the runner-frame'ofI a corn-planter, showing the applied position of theactuating de;

vices for the dropper orvdropping mechanism contemplated by the present invention. Fig. 2 is a detailin perspective of a seed-dropper constructed in.4 accordance with the present invention. Fig. 3 is a Vertical sectional View ofthe dropping mechansm in its applied .p'osition. Fig.' et is a transverse sectional view on the line o: 'of Fig. Fig. 5 is a horizontal sectional ,view on 'theline 5 of Fig. 4. Fig. 6 is a detail plan view of the actuatingdrum which is preferably associated "with in the usual Way, and the seed-dropping mechanism arranged within the seedhoxes or hoppers 4 is designed-'to be operated from the ordinary reciprocatory dropper-actuatin g 'har 5, which bar is reciprocated by any ,Wellknown check-row or other operating mechanism which is usually provided for this purpose.

will suiiice for the other.

Referring particularly to Fig. of the drawings, it will be' observed that the bottom of Veach seedbox is provided with a wheel-opening 6, disposed transversely of the planterrameand receiving'therein the fixed or stationary deliveryrhead, preferably in the form of a disk or circular block and provided therein with a vertical diametric seed-opening S, having4 flared end y portions communicating, respectively, with the interior of the seedbox 4,- and Ythe delivery tube or spout 3. The stationary or iixed delivery-disk 7 loosely receives thereon a hollow oscillatory dropping wheel 9, workin g loosely' within the wheel-opening 6 and essentially comprising the opposite circular heads 10 and a rim 11, interposed between said .headsand secured to the peripheral edges. thereof to complete the hollow wheel, which registers upon the disk 7 and at the same time permits of the passage of seed therethrough. The rim 11 of the oscillatory dropping-.wheel is provided in the lower side thereof with an elongated discharge opening orslot 12 'in communication A openings 13, adapted to be alternately thrown into commu nication with the upper end of the seed-opening 8 through the disk or wheel 7.

lt will be noted that the bottom discharge opening or slot l2 is sufiiciently long to uncover thelowerend oftheseedopening 8 in 'allpositions of 4the dropping-wheeh In order to permit the droppingfwlieelto turn freely and independently of? the stationary IOO disk or head 7 the said wheel hasproj ected centrally from thelopposite heads or sidesv thereof the diametrically opposite spindles 14, which turn in bearings 'formed at opposite sides of the opening (i, as plainly shown in Fig. at ofthe drawings, and to properly secure the disk or head 7 `against axial Inovement the said disk has fit-ted therein a pair vof supporting-pins 15, arranged atfdiainetrically opposite sides of the center of the diskv or head and having their standards iittingin Vzoy the bottom of the seedboxes at opposite sides of the wheel-opening 6. To permit of the movement of thedropper-wheel over the supporting-pins 15, thev heads vor the side portions 'of the dropping-wheel are each provided with a pair of oppositely-located and reversely-arran ged arcuate slots 1G, y which receive the said pins 15. In this connection vit will be observed that the pins 15 not only provide for properly supporting the vdisk orV head'7 in place, but also act in the capacity of vstop-pins to stop or limit the oscillation of the dropping-Wheel in both directions.

Each dropping-wheel J is preferably oper--A v rocatory dropper-actuatingbar 5, so that when the usual check-row or other operating mechanism for the bar 5 transfers motion to said bar said bar will in turn simultaneously oscillate the oppositelylocated drums 17, which will in turn transfer an oscillatory inotion to their respective dropping wheels through the medium of the operating-wires or other equivalent flexible connections 21 and 22, respectively. The operating-wires or equivalent iiexible connections 21 and 22 are respectively arranged at the upper and lower sides of each dropping-Wheel and its actuating-drum 17, it being noted that the upper operating-wire 21 passes over the upper side of the actuating-drum 17 and also passe-s over the upper side of the droppingwheel, while the lower operating-wire 22 is arranged in reverse relation, although both of the operating-Wires are fastened at their extremities respectively to the dropping-wheel and its actuating-drum. By reason of thus connecting` the operating wires with each dropping-Wheel and its actuating-dru m a positive oscillation will be imparted to the dropping-wheel when its actu ating-dru in oscillates in either direction.. To provide for properly retaining the operating-wires 21 and 22 upon cach dropping-Wheel and its actuating-drum and thereby preventing lateral displacement of the wires, each dropping-Wheel and its actuating-drum is preferably provided with a pair of peripheral retaining-grooves 24 and 25, located, respectively, at the opposite side edges of the wheel, as plainly shown in Figs.

2 and 6 of the drawings.

Arranged within each of thc seedboxes is an arched guard or shield 2G, extending over the upper side of the dropping-wheel and provided with flanged ends 27, secured upon the v rim of the box.

At its flanged-ends the arched shield 26 is provided with openings 2S in communication with seed-notches 29, formed at opposite ends of the Wheel-opening (S to facilitate the passage of seed into the feed-openings v13 of the dropping-wheel, which construction maybe plainly seen from Fig. 3 of the drawings. In the operation of the machine through the medium of the connections described the dropping-Wheels are oscillated f so as to alternately bring their separate feed- 'openin gs 13 in register with the opposite seednotches 29, so that said notches will receive or take up the seed and elevate ,the same to the upper endy of the seed-opening S,through which and the discharge opening-or slot 12 the seed falls into the seed-delivery tube or spout 3. As the shield orguard completely incloses the dropping-wheel, the seed has access vto the pockets 13 therein only through the comparatively small opening 28, formed vin the shield, and the seedis directed into said pockvets thro ughy the downwardly-inclined notches 29 in a'ma'nuer to-prevent catching and con-v sequent breaking or damage of the seed. It will be seen that the peripheral edge of the iixed disk 7 provides a bottom for the pockets 13 until the latter are alined with the vertical opening S in the disk, when the seed is free to drop through the same.

Changes in the form, proportion, size, and the minor details of construction Within the scope of the appended claims may he resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

1. In a seed-dropper for planters, the combination with a seedbox having a bottom opening, of a stationary disk supported within said opening and having a seed-opening extending therethrough, and a hollow oscillatory dropping-Wheel loosely Working over and completely housing therein the stationary disk, and provided in its lower side with an elongated discharge-slot and in t-he upper side with a pair of spaced feed-openings, said dropping-wh eel having the inclosing side portions thereof engaged with suitable stops to limit the oscillation thereof, substantially as set forth.

2. In a seed-dropper for planters, the combination With a seedbox having a bottom opening, of an oscillatory dropping- Wheel supported within said opening, an oscillatory actuating-drum supported exteriorly of the seedbox, means for oscillating the said drum, and flexible Operating connections between the drum and the dropping-wheel, substantially as set forth.

In a seed-dropper for planters, the combination with a seedbox, of an oscillatory droppin g-'wheel su pported within the bottom IIC said opening with seed-notches, of a droppin'gwheel Within said opening,and an arched guard arranged Within the box over the dropping-wheel, and provided at its ends with openings. in communication with said seednotehes, substantially as set forth.

In testimony that I claim the foregoing as.

my own I have hereto affixed my signature in the presence of two Witnesses.
